A diamond composed of 100% pure carbon without any impurities is incredibly rare. Almost all diamonds contain some degree of colour impurity, known as inclusions, typically caused by
long-drawn-out traces of nitrogen, boron or hydrogen which are present while the gems are
forming deep within the earth.
These natural birthmarks are often not visible to the naked eye, but can affect the transparency
or brilliance of a diamond. A 6-category scale is used to grade diamonds based on their clarity
The Clarity Scale
No inclusions or blemishes visible under 100x magnification. The stone is completely clear.
INTERNALLY FLAWLESS (IF)
No inclusions visible under 100x magnification. There are however very small blemishes, noticeable to only experts.
VERY VERY SLIGHTLY INCLUDED (VVS1-VVS2)
Incredibly slight inclusions only noticeable to experts under a 10x microscope.
VERY SLIGHTLY INCLUDED (VS1-VS2)
Minor inclusions that are observed with effort under 10x magnification.
SLIGHTLY INCLUDED (SI1-SI2)
Inclusions that are visible under 10x magnification.
INCLUDED (I1, I2, I3)
Inclusions that are obvious under 10x magnification and potentially visible to the naked eye
